i spent last year working construction with a bunch of guys who went to trade school for various specialites nice guys hard working and they made a good living many of them were very conservative very relgious and extremely racist though they kept spouting government conspiracy theories and blaming everything on that big eared nigger in the white house i dont know its just anecdotal but it lend credibility towards the notion that these people have never once been pushed out of the comfort zone and it certainly made me want to seek another line of employment
